There is a newer version: 8.6.0.37351

Rather than creating a boxed primitive from a String to extract the primitive value, use the relevant parse method instead. It will be clearer and more efficient.

Noncompliant Code Example
String myNum = "12.2";

float f = new Float(myNum).floatValue();  // Noncompliant; creates & discards a Float


Compliant Solution
String myNum = "12.2";

float f = Float.parseFloat(myNum);
